I have attempted to incorporate the under-utilized legume seeds in the animal feeds as a source of alternative protein. I have included the effectively treated seed samples of under-utilized legumes as a protein ingredient in the poultry diet by replacing the conventional protein source, the soybean meal at various levels. I have analyzed the effect of replacement of conventional protein source by the under-utilized legume proteins in the diets of broiler birds on the growth performance of the commercial type broilers such as feed intake, body weight gain, feed conversion ratio and protein efficiency ratio. Through my research work, I have identified the suitable processing methods to remove/reduce the levels of antinutritional constituents present in the under-utilized legume seeds and I have also recommended the suitable inclusion level of the under-utilized legume grains in the poultry diets, which will exhibited better growth performance of the poultry birds.

I have been worked on the nutritional quality of certain under-utilized legume seeds such as Abrus precatorius, Acacia nilotica, Acacia leucopholea, Bauhinia purpurea, Canavalia ensiformis, Canavalia gladiata, Cassia hirsuta, Cassia floribunda, Entada scandens, Mucuna monosperma, Mucuna pruriens, Tamarindus indica, Sesbania bispinosa, Erythrina indica, Pongamia pinnata, Xylia xylocarpa etc. I have analyzed the proximate composition, total proteins, different solubility classes of seed storage proteins, molecular characterization of seed storage proteins through electrophoretic technique, amino acid composition, mineral composition, vitamin composition and in vitro protein digestibility. I have also analyzed various antinutritional compounds present in the under-utilized legume seeds such as total free phenolics, tannins, non-protein toxic amino acids (L-Dopa), phytic acid, oligosaccharides (flatulence factors), haemagglutinating activity of lectins, trypsin inhibitor activity and amylase inhibitor activity.
I have also evaluated the effect of various simple and cost-effective processing methods on the levels of antinutritional compounds of various under-utilized legumes. Moreover, I have analyzed the biological value of the seed proteins of the under-utilized legumes through rat feeding trials by determining the effect of feeding the rats with the diets containing 10% level of both raw and differentially processed under-utilized legume seeds as a protein source on the growth performance of the rats such as feed intake, body weight gain, feed conversion ratio and protein efficiency ratio. Further, the protein quality of the under-utilized legume seeds also were analyzed in terms of true digestibility, biological value, net protein utilization and utilizable proteins. |

To meet the protein requirements in the developing countries, where animal protein is also grossly inadequate and relatively expensive, the recent research efforts are being geared towards finding out an alternative/additional protein source. Limitations of protein supply make an urgent need to explore other alternative, additional or novel protein foods for the world of tomorrow. Food Scientists and nutritionists all around the world have been attempted to approach this complex problem by developing novel protein foods such as algal foods, single cell proteins, insect proteins and leaf protein concentrates. In this context, the seed materials of under-utilized legumes recives more attention as an alternative protein source. Recently, sincere and concerted efforts are being made to identify and evaluate the under-utilized legume seeds as an alternative/additional protein, whose potential remains untapped to the extent that they deserves.
Over the past few decades, research efforts have been directed to evaluate the possibilities of utilization of nutritional quality of the under-explored legume seeds in the animal feed. The seeds of under-utilized legumes are potential substitutes for soybean meal because of the similarity in their amino acid and energy profiles. Some of the under-utilized legume varieties are well suited to subtropical regions and showed promise as competitive sources of protein for livestock. Agronomists recognized that increased cultivation and utilization of such under-utilized grain legumes would make a valuable contribution to sustainable agriculture. In this context, in India I have been working with a view to evaluate the nutritional value and protein quality of seed materials of various under-utilized legumes for the utilization as an alternative protein source in the diets of monogastric animals such as poultry, fishes etc. |

I have been working in the area of “Evaluation of nutritional value and protein quality of certain under-utilized legume seeds and their utilization as an alternative protein source in the diets of monogastric animals” for the past 8 years.
At present there will be an increasing interest towards finding out an economic and alternative/additional source of protein for the livestock animals. Inevitably there will be an increase in the world-wide demand for protein source for the livestock feed, which is expected to be met largely by common legume grains. Soybean meal and fish meal currently occupy a central role in the feeding of monogastric animals in many developed countries. Increasing demand for protein for livestock industries particularly in the developing countries, coupled with a relatively high cost of conventional protein ingredients has turned the attention of animal nutritionists for the exploitation of non-conventional legume seeds as a protein ingredient, which the region has in abundance. Although the conventional legume seeds play a key role as a cheap source of protein in the diets of both human beings/animals, their production was not sufficient to meet the requirements of increasing human population and expanding livestock industries, particularly in the developing countries. Moreover, there was a competition existed between human beings and livestock animals in consuming the conventional legume grains as their protein source. Due to unavailability and higher cost of the conventional legume proteins, there was a inappropriate increase in the cost of the animal feeds, which was found to affect the growth of the livestock industries in many developing countries. |
